Ian Gudger 002f1d4aae Allow waiting for LinkEndpoint worker goroutines to finish. 
Previously, the only safe way to use an fdbased endpoint was to leak the FD.
This change makes it possible to safely close the FD.

This is the first step towards having stoppable stacks.

Updates #837

Michael Pratt df5d377521 Remove go_test from go_stateify and go_marshal 
They are no-ops, so the standard rule works fine.

Nicolas Lacasse bfd9f75ba4 Set the FilesytemType in MountSource from the Filesystem. 
And stop storing the Filesystem in the MountSource.

This allows us to decouple the MountSource filesystem type from the name of the
filesystem.

Andrei Vagin f4105ac21a netstack/fdbased: add generic segmentation offload (GSO) support 
The linux packet socket can handle GSO packets, so we can segment packets to
64K instead of the MTU which is usually 1500.

Here are numbers for the nginx-1m test:
runsc:		579330.01 [Kbytes/sec] received
runsc-gso:	1794121.66 [Kbytes/sec] received
runc:		2122139.06 [Kbytes/sec] received

and for tcp_benchmark:

$ tcp_benchmark  --duration 15   --ideal
[  4]  0.0-15.0 sec  86647 MBytes  48456 Mbits/sec

$ tcp_benchmark --client --duration 15   --ideal
[  4]  0.0-15.0 sec  2173 MBytes  1214 Mbits/sec

$ tcp_benchmark --client --duration 15   --ideal --gso 65536
[  4]  0.0-15.0 sec  19357 MBytes  10825 Mbits/sec

Googler 12d9cf6fab Adds a WriteRawPacket method to the InjectableLinkEndpoint interface. 
Also exposes ipv4.MaxTotalSize since it is a generally useful constant.
